In the past, testing usually took a week, but with this artifact, the results can be obtained on site in 30 seconds. "On November 12th, traffic and transportation comprehensive administrative law enforcement personnel in Zhenjiang City used solid waste heavy metal rapid detection equipment to conduct on-site sampling of water transport ships and determine the results. It is understood that this high-tech application of water law enforcement is also considered * in Jiangsu Province.

The author followed traffic law enforcement officers to sample the cargo loaded on a cargo ship. After putting it into a special plastic bag, the law enforcement officers first self checked the rapid inspection equipment. After calibration, they lightly touched the sample and pressed the start button. In just 30 seconds, the electronic screen at the end of the equipment displayed the test results, showing the sample elements and content. If there is a phenomenon of heavy metal exceeding the standard, the display of the exceeding elements will turn red. From sampling and equipment self inspection to final determination, it takes less than 5 minutes. This small technological "artifact" has become a "weapon" for water law enforcement, improving regulatory efficiency and enhancing the deterrent power of traffic law enforcement.

Due to the high cost of hazardous waste disposal, illegal transfer and dumping by waterways often occur, polluting the water environment and becoming a "hidden danger" to shipping safety. In previous law enforcement inspections, traffic law enforcement officers mostly relied on their accumulated "old experience" to identify suspected ships based on their appearance and odor, contact environmental protection departments to take samples and send them for inspection on site, and wait for a third party to issue test results, which usually takes one week. During this period, the ships can only be temporarily detained. The results can be obtained on the spot without having to dock for a long time, saving transportation time, "said Master Ma, a boatman, with a smile and emotion after observing the scene. The rapid inspection equipment utilizes technological means to greatly solve the difficulties encountered by traffic law enforcement in judgment and inspection, facilitating boat people and facilitating the smooth implementation of on-site law enforcement.

At present, traffic law enforcement personnel have deployed two sets of ship solid waste heavy metal rapid inspection equipment on the upstream and downstream of the Zhenjiang section of the Sunan Canal, forming an effective "closed-loop" management at the inlet and outlet of the jurisdictional waters. For ships with test results exceeding the standard, they will be transferred to the environmental protection department for further processing in accordance with the hazardous waste disposal measures. We will resolutely prevent the illegal transfer and dumping of solid and hazardous waste by waterways, effectively ensure the safety of the ecological environment of the water areas along the route, and take practical actions to protect the clear waters and blue sky, and defend the beautiful canal.
